/*!
  The PopupButton represents an enum type in a compact, popup-based form.
  A PopupButton instance at rest is a simple push button showing an icon
  which represents the stored enum. As the user clicks on the button, a
  popup appears showing a description and, optionally, an icon of the
  selectable enum values.
